TRAILER-TRUCK FOR LOCMOTIVES.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed March 1, 1909. Serial No. 480,501.

To all whom it may concern:

Be it known that I, WILLI/nir F. Krnsnr., Jr., a citizen olf the `UnitedStates, residing at Altoona, in. the county oi Blair and State o1llennsylvania, have invented certain new and uselul. Improvements inrirailcrllrucks for Locomotives, oi which the following is aspecification.

This invention relates to improvements in trucks for supportinglocomotive boilers at the rear of the back drivers; one oiE my objectsbeing to provide a truck, the frame of which will be lulcrumed in lirontci the ashpan, the rear portion of the frame being susceptible of anydesirable side motion, and the frame itself acting as an equalizerbetween the rear end of the back driver springs and the trailer axlesprings.

A further obj ect is to provide a novel iriction bearing for the mainframe where it rests upon the truck frame, whereby there will beintroduced a certain amount of lirictional resistance to the sidemovement oi the truck, for the purpose of compelling the front truck ofthe locomotive to operate to its limit of side motion before thetrailer' truck has any side motion: and a 'linal object is to provide acentering device for returning the trailer truck to central positionafter movement to one side or the other, in rounding curves, and thelike.

I attain my objects by constructing the truck in the manner illustratedin the accompanyin g drawings, in which-- Figure 1 represents a sideelevation of the truck, as applied. to the rear portion of a locomotiveframe,- Fig. 2, a plan view of the same, portions being shown insection; Fig. 3, a liront elevation ot the truck, parts being shownsectioned on the line .Ce-x in Fig. 2; Fig. li, a rear elevation oiI thetruck, with onehalf of the centering device shown in section Figs. 5 and6, a plan view and side elevation, respectively, of the truck frame;Fig. 7, a detail showing a sectional view of the hanger connectionsbetween the truck springs and pedestals, on the line y-{l/ in. Fig. 1; Fig. 8, a similar sectional view of the hanger connections between theback driver springs and the truck trame on the line e-e in Fig. 1; Fig.9, a detail showing the bushing for the fulcrum eye where the trailertruck is coupled to the main frame and Figs. 10 and 11, details showingthe spring hanger coupling bars.

Like numerals designate like parts in the several views.

As hereinillustrated the main i' ram e oi' the locomotive at the rearci' the back drivers consists ol' two parts, 1 and 2, spliced togetherat 3, the i'ramc members 2 being carried to the rear and lastened to across piece l, to which the tank is coupled. The lirebox is supportedover this portion ol the locomotive sidei'rames, as indicated at 5. Theaxle i'or the back driver is shown at 7 in Fig. 1, axle boxes 6 thereforbeing mounted in the i'rame members 1, in the usual mans ner, withsupports :li'or the springs E) resting upon the axle boxes, the iorwardends ol' said springs being coupled to the sidel'rames in any approvedmanner. The trailer truck axle 10 is journaled in axle boxes 11 outsidethe truck wheels, said axle boxes being slidably mounted betweenpedestals 12 and 13. These pedcstals are prelerM ably oli' cast steel,the rear pedcstals 13 being integrally oined by the flanged and ribbedcross piece 14, which constitutes the rear end of the trailer truckiframe. The pedestals 12 and 13 are fastened together by goose necksformed on the sideplates 16 o1'l the truck frame, said side plates beingin pairs and the goose/neck portions thereol' being riveted to theinward. and outward sides ol' the pedestals. These sideplate pairs 16are bent so as to approach one another toward the forward end of thetruck, where the two members oli' each pair are brought together andproject forward inline with and beneath the main sidel'rames 1 at 17.The Yl'orward ends oi these united plates are carried down ward somewhatand notched to rest upon cross bars 18, which are supported by links 19at each side, said links being coupled at their upward ends, by pins 20,to single links 21, which pass through slots provided there- Vlor in thesprings 9, said links 21 being sup ported upon the springs by the crossbars 22, notched at their upward. ends to receive the links, and iittedinto notches in the springs at their lower ends, whereby articulatedhangers are provided between the springs 0 and the side members ol' thetruck l'rame, to permit et the forward and back movements ol' said truckframes, when the truck turns upon its 'l'ulcruin The pedestals 12 and 13are coupled together at their lower ends by the bolt 23, which passesthrough a filling piece 24. Halt elliptic springs 25 rest upon y 1helgoosenecks f s1de wings being slotted to receive the bars 28 in themanner illustrated in Fig. i7, and the links being also slotted to`permit said cross bars to be passed therethrough in assembling theparts. l i

At .the points Where the mainframe members l and 2 `are splicedtogether, there are bolted in, by the splice bolts, brackets 29, whichproject outwardly at each side ol'` the locomotive, said bracketsresting upon plano convex disks 30, which inturn-are mounted 1n concavebearings formed on the t upper Sides oi the castings 32, which. areriveted 1n` between the side plates "16 of the truck frame. The brackets2Q are provided with suitable grease cups anil passages wherebylubricant may be fed to radial grooves` formed on the upper and lowerfaces of the disks 30, the lower grooves beingcoimected to the upperyones by a central duct, as shown in Figs. 2 and 3, side or the other ofthe main frame, the disks 3() slide across the under l'ace ol' thebrackets 2Q, and the convex surfaces ol' said disks permit the verticaltilting ot' the truck l'rame relatively to the main frame members. Whilethe lubricating oll this bearing provides l'or l'reedom o'll motionwit-hout cutting and wear between parts, there is still sulli` cient'friction generated to attain the object heretofore speci-lied. Thelocation oi these brackets and bearings determines the equalization ofthe load between the back driver and the truck wheels.

The sidewise motion of the truck takes place around the fulcrum pin 37,carried by the cross piece 35, which is a casting bolted in between theframe members l at the rear of the back driver aXle, said cross piecebeing provided with an opening 36, into which a lorward projection, oreye prece, 34 enters from the fulcrum piece 33, which is riveted inbetween the forward ends 17 ol the truck sideplates; said openingpermitting a lim through ol' the inward hanger links l19, the

followers e3; said followers being forced outwardly under thetension ofa spring to ene i gage bearingplates e5, fastened tothe inward sides.of' the main frame members 2.

` Movement ol the truck frame to one .side or b the other causes one ofthese lollowers to be` pushed inward. against the tension el' spring 44said spring actingthrough the follower to return the truck `frame tecentral position,

when relieved from side thrust, the intention being that thespringcapacity shall bejust suiiicient` to overcome the `friction at thebearing disks 30. b

Thev whole brake operating mechanism for the` truck, including thebrakefcylinder, is hung from the cross piece 14, as `shown in Figs l, 2, ande', said'eross piece having bolted to an under plate, formed thereon aty46,

ythe `brake cylinder 47, which is connected te the mam an' system by anysuitable llemble connection, not shown. A piston rod is coupled at 48 toa cross bar llt), towhieh, at

each end are coupled links 50,'which in turn are coupled to the brakelevers 5l, said brake levers being ulcrumed in brackets 52, bolted tothe under flange of the cross piece le.

The brake clogs 53 are coupled to these levers 5l, as shown in Fig. 4,and are hung from brackets 55 by means of links 54. The couphn@- links50 are su orted b uide brackets 56, attached to the forwardly projectingwebs on the cross piecele between the sup porting bedplates 40 and 46.
